Characterization of Particle Size and Composition of Respirable Coal Mine Dust [PDF]
Minerals, 2021 Respirable coal mine dust (RCMD) particles, particularly the nano-sized fraction (<1 μm) of the RCMD if present, can cause severe lung diseases in coal miners. Characterization of both the particle size and chemical composition of such RCMD particles remains a work in progress, in particular, with respect to the nano-sized fraction of RCMD.

Chemistry and particle size distribution of respirable coal dust in underground mines in Central Eastern Europe [PDF]
International Journal of Coal Science & Technology, 2022 AbstractDespite international efforts to limit worker exposure to coal dust, it continues to impact the health of thousands of miners across Europe. Airborne coal dust has been studied to improve risk models and its control to protect workers. Particle size distribution analyses shows that using spraying systems to suppress airborne dusts can reduce ...
